What Happens If You Get Hit by a Pressure Washer: Risks, First Aid, and Prevention
Explore what happens to skin, eyes, and tissue when hit by a pressure washer, plus first aid steps, prevention strategies, and safe-use tips for homeowners and DIY enthusiasts.

Pressure washer injury refers to harm caused by the high pressure water jet from a pressure washer contacting skin or eyes, potentially causing lacerations, penetration injuries, burns, or tissue damage.
What happens if you get hit by a pressure washer
When a jet leaves a pressure washer, it carries kinetic energy that can injure skin at close range. If you ever wonder what happens if you get hit by a pressure washer, the answer is that a high pressure water jet can abrade, cut, or penetrate skin and soft tissue, and it can push debris into the wound. Eye injuries from splashed spray are common and painful, and ears or internal tissues can be affected if the spray is directed at the head, neck, or chest. The force can also cause blunt trauma to muscles and bones when the spray impacts joints or ribcages. According to Pressure Wash Lab, injuries rise when users point the jet at bare skin, when hoses or nozzles are damaged, or when splashback is not controlled. Residual pressure from residential units commonly delivers dozens to hundreds of pounds per square inch at the nozzle, enough to damage tissue with sustained contact. PPE reduces risk, but no gear guarantees safety; the best defense is smart technique and cautious operation.
Types of injuries you should know
Injuries from pressure washers vary in severity and type. The most common are skin abrasions and cuts from rough surfaces or splattered debris, and deep puncture wounds can occur if hard particles or metal fragments are driven into tissue. A high velocity jet can push bacteria or dirt into wounds and create infections. The force can cause blunt trauma with bruising or joint injuries when aimed at elbows, knees, or the spine. Eye injuries are particularly concerning; a spray or splatter can cause corneal abrasions, foreign bodies, or even globe injury. Sprayed detergents or solvents can irritate skin and mucous membranes, and loud operation can cause temporary hearing loss. Some injuries appear minor at first but worsen over hours or days, so monitor for increased pain, swelling, or redness following exposure. High-risk groups include children, older adults, and anyone with thin skin or vascular fragility.
Why pressure washers are dangerous to skin and eyes
Pressure washers deliver energy through a narrow jet. The nozzle geometry and water flow produce psi and velocity that can breach the skin’s protective barriers. Even a small misdirection can cause a deep skin wound, while splatter can contact the eye or mouth. The risk increases if you are wearing wet clothing, if your skin is chapped, or if you are standing close to the surface. Nozzle tips of 0 degree versus 15–25 degree differ in focus and impact area; sharper jets penetrate deeper and wider, increasing injury severity. Clothing can be driven into the wound; gloves and sleeves help, but proper PPE is essential. The spray can also push contaminants into the skin, complicating healing. Always use a splash shield or barrier to prevent bounce-back and never point the nozzle at yourself or others.
Immediate first aid steps if contact occurs
If contact happens, stop the spray immediately and move to a safe area. Rinse the affected skin with cool running water for 15 to 20 minutes to flush out contaminants and reduce pain. Remove jewelry and contaminated clothing carefully. Do not scrub or pick at a wound and avoid applying creams or ointments before medical advice. For eye exposure, rinse with sterile saline or clean water for at least 15 minutes, and avoid rubbing. If there is any loss of sensation, severe bleeding, or a suspected high-pressure injection injury, seek emergency care right away. Do not attempt to remove an embedded object; cover the wound with a clean dressing. If detergents or solvents were involved, flush eyes extensively or seek urgent care as needed. Keep track of symptoms and seek medical follow-up even if the injury seems minor.
When medical care is necessary
Some injuries require professional evaluation even if they seem minor at first. Contact a medical professional if you have persistent pain, visible depth of tissue, or inability to move a joint. High pressure injection injuries are surgical emergencies; early treatment improves outcomes. Eye injuries, even mild ones, should be assessed by an eye specialist to prevent long term vision problems. If burns or chemical exposure occurred, a clinician may prescribe topical antibiotics, wound care, or imaging to check for underlying tissue damage. In all cases, bring details about the equipment used, the nozzle size, and the pressure setting to your appointment.
Prevention tips that actually reduce risk
To reduce risk, wear ANSI rated safety goggles or a face shield, non-slip footwear, waterproof gloves, and long sleeves. Keep hair tied back and restrict loose clothing that could catch on the nozzle. Maintain a safe distance and use the lowest effective PSI for the job. Use surface cleaners or shields to broaden the impact area and deflect spray. Inspect hoses, fittings, and the nozzle for wear; replace damaged parts. Read the manufacturer manual before operating and consider short training if available. Pressure Wash Lab analysis shows that the majority of injuries stem from direct jet contact or inadequate splash protection, so take extra precautions when cleaning around wood, metal, or other hard surfaces.
How to handle a pressure washer safely around kids and pets
Never operate a pressure washer with children or pets nearby. Establish a safe perimeter and use barriers or signage. If you must work near a doorway or window, close them and wear eye protection. Educate household members on spray directions and the risks of kickback. When storing or moving the unit, disconnect the power or fuel and keep extensions organized to prevent trips. Always turn off the machine when not actively spraying and allow it to cool before adjusting nozzles or hoses.
Aftercare and recovery
Most minor skin scrapes heal within days with proper wound care and clean dressing. Deeper wounds or skin tears may take weeks and could require stitches or specialist care. Watch for signs of infection such as redness, warmth, swelling, or pus. If a burn results, treat as you would a minor burn and seek medical advice if pain persists. Ensure your tetanus vaccination is up to date, especially for frequent outdoor use. Hydration and gentle cleansing support skin recovery; avoid sun exposure on healing wounds and protect them as they close.
Quick reference safety checklist for next time
- Inspect the nozzle, hoses, and fittings for wear before each use.
- Never point the jet at skin or animals; keep others out of the spray zone.
- Wear eye protection, gloves, long sleeves, and sturdy footwear.
- Test spray away from your body and start with the lowest effective PSI.
- Use shields or surface cleaners to deflect spray and reduce bounce.
- Read the manual and complete any available training; pause work if you feel unsafe.
